Study on the chaotic motion of a double pendulum with computer vision method
This article introduced a method of how to use computer vision method to measure the states of a double pendulum contactlessly,and investigated the motion law of the double pendulum,particularly chaotic motion law with the proposed method.The results indicated that as the initial en-ergy of the double pendulum increased with the increasing initial angle,the system gradually transited from a periodic motion to a quasiperiodic motion,and finally to a chaotic motion.The energy of the pendulum was a crucial factor for the appearance of chaotic motion.Double pendulum was a good can-didate for the study of chaotic phenomena in the course of college physics experiment for its simple structure,straightforward phenomena and low costing.In addition,the computer vision method could realize a contactless measurement on the movement state of the double pendulum.
